TECHNICAL FIELD

The present disclosure relates to an oral cleaning tool, and more particularly to a multifunctional visual oral cleaning instrument for cleaning tooth gaps.

BACKGROUND

Due to age, pathology and other reasons, it is easy to cause gingival recession and enlargement of tooth gaps, which can easily cause food residues. If the food residues cannot be cleaned in time, bad breath will be generated on the one hand, and on the other hand, it is easy to cause various dental diseases and oral diseases, especially periodontitis. In addition, when people eat fish, the fish bones will sometimes stick into the gingivae and need to be removed in time.

In response to this situation, various toothbrushes, dental flosses, interdental brushes and other products have been developed on the market for users to choose at present. Although various structures of products with different sizes, such as toothbrushes, dental flosses, interdental brushes and the like exist on the market today, the existing products are generally disadvantageous in that they are not easily viewed. Especially when the position to be cleaned is deep in the oral cavity, such as the gap between the third molar and the second molar, or the gap between the second molar and the first molar, or the gap between the first molar and the second premolar, if the light of the cleaned part is very dim, the position to be cleaned cannot be seen clearly in general cases, so that the user can only operate by feeling inconveniently, and cannot know whether the position to be cleaned to is cleaned completely, which can easily cause gingival bleeding or other accidental injuries.

In order to overcome the disadvantages of the prior art, it is necessary to develop a visual oral cleaning tool through which the inside of the oral cavity, especially deep in the oral cavity, can be viewed clearly and oral cleaning can be performed under direct vision.

C. the dental floss 100 is mounted on the oral viewer 200 through the connecting mechanism 300.

In particular, the dental floss 100 may be detachably mounted on the oral viewer 200 through the connecting mechanism 300.

The floss 11 of the dental floss 100 is within the visual field of the viewing system 24 of the oral viewer 200. Thus, the dental floss and the gap between teeth can be clearly seen, so that tooth gaps can be conveniently cleaned and treated under direct vision during use, and the cleaning effect of the tooth gaps can be viewed and recorded in real time.

An included angle β between the floss 11 of the dental floss 100 and the center line of a head 21-1 of the housing of the oral viewer 200 is adjustable. Thus, the included angle β can be adjusted according to the angles of the tooth gaps of different parts, so that the dental floss can conveniently enter the tooth gaps and clean the tooth gaps. The adjustment of the included angle β can be implemented by adopting a passive mechanical structure, such as a thread structure, or a concave-convex snap fit structure, or a moderate interference fit structure or the like, or by an active electric control manner, such as transmission of a motor or the like.

The connecting mechanism 300 is a detachable mechanical connecting mechanism; the connecting mechanism 300 may be a separate component, and may be arranged on the dental floss 100 or arranged on the oral viewer 200; alternatively, the connecting mechanism 300 may also be a combined mechanical connecting mechanism formed by arranging a part of the detachable mechanical connecting mechanism on the dental floss 100 and the other part on the oral viewer 200. The connecting mechanism 300 may be a separate component, and is respectively connected with the dental floss 100 and the oral viewer 200 to connect the dental floss 100 and the oral viewer 200 into an integral body. The connecting mechanism 300 may also be manufactured as a w % bole with the dental floss 100 or the oral viewer 200, and then connected with the oral view 200 or the dental floss 10 to form an integral body. Regardless of the type of connection, the ultimate goal is to implement a detachable connection between the dental floss 100 and the oral viewer 200. Therefore, the detachable connection between the dental floss 100 and the oral viewer 200 can be implemented as long as the connecting mechanism 300 implements a detachable mechanical connection with one of the dental floss 100 or the oral viewer 200.

The mechanical connecting mechanism may be a concave-convex snap fit connection, or a sliding slot connection, or a pin connection, or a key connection, or a threaded connection, or a screw connection, or a buckle connection, or a hook connection, or an interference fit connection, or the like. Of course, those skilled in the art can select other mechanical connection manners without departing from the protection scope of the present application.

The mounting base 13 of the dental floss 100 is provided with a through hole 13-1, the head 21-1 of the housing of the oral viewer 200 may be embedded in the through hole 13-1, and a detachable connection is formed between the dental floss 100 and the oral viewer 200. When connecting, the head 21-1 of the housing of the oral viewer 200 can be embedded in the through hole 13-1 to form a connection; and when detaching, the dental floss 100 can be removed from the oral viewer 200 by pulling the oral viewer 200 and the dental floss 100 outward with a little force, so the use process is very convenient.

The mounting base 13 of the dental floss 100 is provided with a locating groove 13-2; the connecting mechanism 300 is provided with a locating hook 31 and a locating block 32; the connecting mechanism 300 is mounted on the oral viewer 200 through the locating block 32; and the locating hook 31 on the connecting mechanism 300 is embedded in the locating groove 13-2 of the dental floss 100 to form a concave-convex snap fit connection, and a detachable connection is formed between the dental floss 100 and the oral viewer 200. When detaching, the dental floss 100 can be removed from the oral viewer 200 by pressing down the locating hook 31. The concave-convex snap fit connection manner formed by the locating hook 31 and the locating groove 13-2 is more secure and reliable than the common through hole connection manner due to the effective locating of the locating hook 31.

The mounting base 13 of the dental floss 100 is provided with a thread 13-3; the connecting mechanism 300 is a threaded connecting mechanism 33, and the threaded connecting mechanism 33 is matched with the thread 13-3 and arranged on the head 21-1 of the housing of the oral viewer 200; by rotating the dental floss 100, the thread 13-3 of the dental floss 100 can be mounted on the threaded connecting mechanism 33; and by rotating the dental floss 100 in the opposite direction, the thread 13-3 of the dental floss 100 can be removed from the threaded connecting mechanism 33. At this time, the thread 13-3 on the mounting base 13 may be set as a screw or bolt type, and the threaded connecting mechanism 33 of the connecting mechanism 300 is a corresponding nut; and contrarily, the thread 13-3 on the mounting base 13 may be set as a nut type, and the threaded connecting mechanism 33 of the connecting mechanism 300 is a corresponding screw or bolt.

By rotating the floss 13-3 of the dental floss 100, the included angle δ between the floss 11 of the dental floss 100 and the center line of the head 21-1 of the housing of the oral viewer 200 can be adjusted. Thus, the included angle β can be adjusted in time according to the angles of the tooth gaps of different parts, so that the dental floss can conveniently enter the tooth gaps and clean the tooth gaps.

The connecting mechanism 300 includes a sliding bar 30, a locating hook 31, a left locating hook 31-1, a right locating hook 31-2, a locating block 32 and an antiskid convex line 34; the locating hook 31, the left locating hook 31-1 and the right locating hook 31-2 are arranged at the front end of sliding bar 30, the locating hook 31 is centered, and the left locating hook 31-1 and the right locating hook 31-2 are arranged on both sides respectively; the locating block 32 is positioned in the middle of the sliding bar 30; the antiskid convex line 34 is arranged at the tail of the sliding bar 30; the locating block 32 is mounted in a locating slot 35 of the housing 21 of the oral viewer 200, and a clamping block 36 of the housing 21 of the oral viewer 200 abuts against the tail of the sliding bar 30, so that the connecting mechanism 300 is detachably mounted and fixed to the housing 21 of the oral viewer 200; and the head 21-1 of the housing 21 of the oral viewer 200 is embedded in the through hole 13-1 of the mounting base of the dental floss 100, the locating hook 31 of the connecting mechanism 300 is embedded in the locating groove 13-2 of the mounting base, and the left locating hook 31-1 and the right locating hook 31-2 surround the head 21-1 of the housing 21 of the oral viewer 200 from the left and right sides.

During mounting, the locating block 32 of the connecting mechanism 300 is firstly embedded in the locating slot 35 of the housing 21 of the oral viewer 200, and the sliding bar 30 of the connecting mechanism 300 is slid forward until the clamping block 36 of the housing 21 of the oral viewer 200 is lifted up against the tail of the sliding bar 30; and at this time, the left locating hook 31-1 and the right locating hook 31-2 surround the head 21-1 of the housing 21 of the oral viewer 200 from the left and right sides so as to mount and connect the connecting mechanism 300 onto the oral viewer 200. The design of the antiskid convex line 34 can effectively prevent the sliding bar 30 from slipping when sliding back and forth. The surrounding action of the left locating hook 31-1 and the right locating hook 31-2, and the concave-convex snap fit of the locating block 32 and the locating slot 35 can effectively connect the connecting mechanism 300 firmly to the oral viewer 200.

Then, the head 21-1 of the housing 21 of the oral viewer 200 is embedded in the through hole 13-1 of the mounting base of the dental floss 100, and by pushing the dental floss 100 toward the connecting mechanism 300, the locating hook 31 of the connecting mechanism 300 can be embedded in the locating groove 13-2 of the mounting base 13.

When detaching, the top of the locating hook 31 of the connecting mechanism 300 is pressed down to withdraw the dental floss 100, so that the concave-convex snap fit between the connecting mechanism 300 and the dental floss 100 can be released. When it is necessary to further remove the connecting mechanism 300 from the oral viewer 200, the sliding bar 30 is forced backwards, the clamping block 36 of the oral viewer 200 is pressed down, and the locating block 32 of the connecting mechanism 300 is withdrawn from the locating slot 35 of the oral viewer 200 until the connection of the connecting mechanism 300 and the oral viewer 200 is completely released.

Since the locating block 32 of the connecting mechanism 300 adopts an inverted T-shaped structure, when the T-shaped locating block 32 is embedded in the locating slot 35, the bottom of the inverted T-shaped structure and the locating slot 35 can form a concave-convex snap fit structure, thereby effectively limiting the movement of the connecting mechanism 300 in the vertical direction, and further preventing the connecting mechanism 300 and the oral viewer 200 from departing along the vertical direction during use. Meanwhile, the clamping block 36 of the oral viewer 200 is arranged at the rear end of the connecting mechanism 300; when the clamping block 36 of the oral viewer 200 is lifted up, since the top of the clamping block 36 is higher than the tail of the connecting mechanism 300, the connecting mechanism 300 can be effectively prevented from moving backward; and only when the connecting mechanism 300 is moved backward consciously and forcefully, the connecting mechanism 300 can be released from the oral viewer 200 after withdrawing along the guide surface of the clamping block 36, thereby effectively preventing the dental floss 100 from being accidentally released from the oral viewer 200 due to the fact that the connecting mechanism 300 can easily move backward.

With reference to FIG. 4 and FIG. 4-1, the connecting mechanism 300 includes a sliding bar 30, a locating hook 31, a left locating hook 31-1, a right locating hook 31-2, a locating block 32 and an antiskid convex line 34; the locating hook 31, the left locating hook 31-1 and the right locating hook 31-2 are arranged at the front end of sliding bar 30, the locating hook 31 is centered, and the left locating hook 31-1 and the right locating hook 31-2 are arranged on both sides; the locating block 32 is positioned in the middle of the sliding bar 30; the antiskid convex line 34 is arranged at the tail of the sliding bar 30; the locating block 32 is mounted in a locating slot 35 of the housing 21 of the oral viewer 200, and a clamping block 36 of the housing 21 of the oral viewer 200 abuts against the tail of the sliding bar 30, so that the connecting mechanism 300 is detachably mounted and fixed to the housing 21 of the oral viewer 200; and the head 21-1 of the housing 21 of the oral viewer 200 is embedded in the through hole 13-1 of the mounting base of the dental floss 100, the locating hook 31 of the connecting mechanism 300 is embedded in the locating groove 13-2 of the mounting base, and the left locating hook 31-1 and the right locating hook 31-2 surround the head 21-1 of the housing 21 of the oral viewer 200 from the left and right sides.

With reference to FIG. 1 and FIG. 2, during mounting, the locating block 32 of the connecting mechanism 300 is firstly embedded in the locating slot 35 of the housing 21 of the oral viewer 200, and the sliding bar 30 of the connecting mechanism 300 is slid forward until the clamping block 36 of the housing 21 of the oral viewer 200 is lifted up against the tail of the sliding bar 30; and at this time, the left locating hook 31-1 and the right locating hook 31-2 surround the head 21-1 of the housing 21 of the oral viewer 200 from the left and right sides so as to mount and connect the connecting mechanism 300 onto the oral viewer 200. The antiskid convex line 34 is arranged on the tail of the sliding bar 30, thereby increasing the friction force, and providing convenience for mounting or detaching the connecting mechanism 300. The combination of the surrounding action of the clamping block 36, the left locating hook 31-1 and the right locating hook 31-2 and the concave-convex snap fit of the locating block 32 and the locating slot 35 can effectively connect the connecting mechanism 300 firmly to the oral viewer 200.

Then, the head 21-1 of the housing 21 of the oral viewer 200 is embedded in the through hole 13-1 of the mounting base of the dental floss 100, and by pushing the dental floss 100 toward the connecting mechanism 300, the locating hook 31 of the connecting mechanism 300 may be embedded in the locating groove 13-2 of the mounting base 13, thereby forming the connection and fixation.

When detaching, the top of the locating hook 31 of the connecting mechanism 300 is pressed down to withdraw the dental floss 100, so that the concave-convex snap fit between the connecting mechanism 300 and the dental floss 100 can be released. When it is necessary to further remove the connecting mechanism 300 from the oral viewer 200, the sliding bar 30 is forced backwards, the clamping block 36 of the oral viewer 200 is pressed down, and the locating block 32 of the connecting mechanism 300 is withdrawn from the locating slot 35 of the oral viewer 200 until the connection of the connecting mechanism 300 and the oral viewer 200 is completely released.

Since the locating block 32 of the connecting mechanism 300 adopts an inverted T-shaped structure, when the T-shaped locating block 32 is embedded in the locating slot 35, the bottom of the inverted T-shaped structure and the locating slot 35 can form a concave-convex snap fit structure, thereby effectively limiting the movement of the connecting mechanism 300 in the vertical direction, and further preventing the connecting mechanism 300 and the oral viewer 200 from departing along the vertical direction during use. Meanwhile, the clamping block 36 of the oral viewer 200 is arranged at the rear end of the connecting mechanism 300; when the clamping block 36 of the oral viewer 200 is lifted up, since the top of the clamping block 36 is higher than the tail of the connecting mechanism 300, the connecting mechanism 300 can be effectively prevented from moving backward; and only when the connecting mechanism 300 is moved backward consciously and forcefully, the connecting mechanism 300 can be released from the oral viewer 200 after withdrawing along the guide surface of the clamping block 36, thereby effectively preventing the dental floss 100 from being accidentally released from the oral viewer 200 due to the fact that the connecting mechanism 300 can easily move backward.

Embodiment 10: A Multifunctional Visual Oral Irrigator According to the Present Disclosure

With reference to FIG. 31 to FIG. 34-2, the difference between this embodiment and Embodiment 4 lies in that in this embodiment, the spray head 51 and the spray gun 52 are built into a position near the oral viewer 200 of the viewing system 24, and the water jet sprayed by the spray head 51 of the spray gun 52 is within the visual field of the viewing system 24.

With reference to FIG. 31 to FIG. 34-2, in this embodiment, the front end of the oral viewer 200 is also detachably equipped with an interdental brush 700, or dental floss 100, or toothbrush 600, or oral forceps 400 or any other special tooth cleaning tool through the connecting mechanism 300. The multifunctional visual oral irrigator can be used for rinsing teeth with water under vision, and can also be used for cleaning teeth or tooth gaps under vision, or taking out food residues in the tooth gaps and other positions difficult for cleaning and foreign objects attached to the gingivae by using the interdental brush 700, or the dental floss 100, or the toothbrush 600, or the oral forceps 400.

With reference to FIG. 31 to FIG. 31-2, the front end of the oral viewer 200 is detachably equipped with the interdental brush 700 through the connecting mechanism 300. In this embodiment, the interdental brush 700 is the built-in interdental brush 701. The built-in interdental brush 701 includes a brush body 71 and a delivery device 72. The delivery device 72 includes a guide head 72-1 and a sliding mechanism 72-2, and the guide head 72-1 includes an elbow tube 72-1-1-1. By pushing the sliding mechanism 72-2, the brush body 71 may reciprocate in the elbow tube 72-1-1-1 at the front end of the delivery device 72.

It is particularly important that the direction of the water flow at the spraying of the spray head 51 is substantially the same as the direction along which the brush head 71-1-1 of the interdental brush 700 enters the tooth gap; and thus, while the brush head 71-1-1 of the interdental brush 700 reciprocates in the tooth gap and performs cleaning, the water flow at the spraying point of the spray head 51 can assist in rinsing the food residues in the tooth gap. Therefore, when the oral irrigator 500 is used for rinsing the teeth, the interdental brush 700 can be used for the tooth gap or any narrow gap where the food residues cannot be easily rinsed out with water; the sliding mechanism 72-2 is pushed to drive the brush head 71-1-1 of the brush body 71 to reciprocate under direct vision to push the food residues out of the gap or loosen the food residues; and at this time, through the assisting effect of the water jet sprayed out by the spray head 51 of the oral irrigator 500, direct fixed-point cleaning on the tooth gap difficult to rinse can be effectively performed.

The dental floss 100 includes a floss 11, a bracket 12 and a mounting base 13. The floss 11 of the dental floss 100 is within the visual field of the viewing system. For some especially narrow tooth gaps where the interdental brush 700 cannot enter, the dental floss 100 can be used for further cleaning. During cleaning, when the viewing system 24 is used for viewing, by moving the dental floss 100 back and forth, the small-size floss 11 is utilized to clean the especially narrow tooth gap.

In addition, the direction of the water flow at the spraying point of the spray head 51 is substantially the same as the direction along which the dental floss 100 enters the tooth gap; and thus, while the floss 11 of the dental floss 100 reciprocates in the tooth gap and performs cleaning, the water flow at the spraying point of the spray head 51 can assist in rinsing the food residues in the tooth gap. Therefore, when the oral irrigator 500 is used for rinsing the teeth, the floss 11 of the dental floss 100 can be used for the tooth gap or any narrow gap where the food residues cannot be easily rinsed out with water; the floss 11 of the dental floss 100 is shaken to take the food residues out of the gap or move the food residues under direct vision; and at this time, through the assisting effect of the water jet sprayed out by the spray head 51 of the oral irrigator 500, direct fixed-point cleaning on the tooth gap difficult to rinse can be effectively performed.

With reference to FIG. 33 to FIG. 33-2, the front end of the oral viewer 200 is detachably equipped with the toothbrush 600 through the connecting mechanism 300, and the toothbrush 60M is positioned within the visual field of the viewing system 24. In the tooth brushing process, while the toothbrush 600 is used for brushing teeth, the oral irrigator 500 may be used for rinsing, so that the tooth brushing process is more direct-viewing, and the oral cavity can be cleaned more thoroughly.

With reference to FIG. 34 to FIG. 34-2, the front end of the oral viewer 200 is detachably equipped with the oral forceps 400 through the connecting mechanism 300.
